Our verdict
This WANPTEK is a practical all-rounder: the encoder makes precise adjustment easy, overcurrent protection guards the circuit, and the USB-C port turns it into the desk charger you would otherwise buy separately. It is a sensible choice when bench space is tight and one box has to do two jobs.

Getting started with the WANPTEK 30V 10A Bench Power Supply with USB-C
Use coarse adjustment to get near the voltage you need and fine adjustment to land on it exactly. Set the current limit before connecting a project, and check whether overcurrent protection is set to cut the output or to limit current — the two behave differently when a fault occurs. Keep the USB ports for charging rather than powering sensitive circuits.
Who it's for
Makers who want a bench supply that also charges phones, tools and USB-C devices.

WANPTEK 30V 10A Bench Power Supply with USB-C: common questions
What is OCP on a bench power supply?
Overcurrent protection. When the current exceeds your set limit, the supply acts to protect the circuit — either limiting the current or switching the output off, depending on the model and setting.
Is it safe to charge a phone from the USB-C port?
The quick-charge ports are designed for charging devices, separate from the adjustable main output. Use those ports for phones and gadgets rather than the adjustable terminals.
Coarse and fine adjustment — why both?
Coarse gets you close to the target quickly and fine lets you set it precisely. Together they make it easy to hit an exact voltage such as 3.3V or 5.0V.
